Executive Summary

Network Inventory Advisor version 5.0.26.0 installs a service named 'niaservice' with an unquoted service path vulnerability on Windows systems.

The service path points to 'C:\Program Files (x86)\ClearApps\Network Inventory Advisor\niaservice.exe' but lacks proper quotation marks.

Because of this, local attackers can place malicious executables in directories along the path that contain spaces.

When the service starts or restarts, the system may execute the attacker's malicious code with LocalSystem privileges, allowing privilege escalation.

Impact Analysis

This vulnerability allows local attackers to escalate their privileges on the affected system.

By exploiting the unquoted service path, an attacker can execute arbitrary code with LocalSystem privileges, which is the highest level of privilege on a Windows system.

This can lead to full control over the system, unauthorized access to sensitive data, installation of persistent malware, and disruption of system operations.

Detection Guidance

This vulnerability can be detected by checking the service configuration for the 'niaservice' service installed by Network Inventory Advisor version 5.0.26.0. Specifically, you need to verify if the binary path of the service is unquoted and contains spaces, which allows privilege escalation.

On Windows systems, you can use the following command to check the service path for unquoted paths:

• sc qc niaservice

If the path returned by this command contains spaces and is not enclosed in quotation marks, the system is vulnerable. For example, a path like C:\Program Files (x86)\ClearApps\Network Inventory Advisor\niaservice.exe without quotes is vulnerable.

Mitigation Strategies

To mitigate this vulnerability immediately, you should correct the unquoted service path by enclosing the binary path in quotation marks. This prevents the system from executing malicious executables placed in intermediate directories.

Alternatively, you can update or patch Network Inventory Advisor to a version where this issue is fixed, if available.

As a temporary workaround, restrict local user permissions to prevent placing executables in directories along the service path.
